SONY BRAVIA 3 vs TCL A400 PRO

Bravia 3 does not hide the fact that it belongs to a group of TVs that are rather modest in terms of brightness. Our measurements showed around 370 nits, which is a value balancing on the brink where any HDR effect can still be discussed. For some, this is an acceptable level, while for others it is more typical for SDR materials, where spectacular flashes or vivid contrasts are not expected. The impression is that this is not a TV for those focused on the highest image quality in demanding film content. However, this does not mean that there are no advantages to be found here. Compared to its predecessor, the X75WL, the Bravia 3 has gained an additional PFS filter, which works similarly to solutions known from QLED technology. Thanks to this, the DCI-P3 color gamut has been significantly expanded, reaching over 91 percent, which in practice results in more saturated colours and a more pleasing texture of the image. As a result, even everyday content looks a bit more vibrant, and films and series can surprise with their colourful presentation, despite limitations in brightness itself.

The TCL A400 Pro is a moderately bright TV. Its peak brightness reaches around 600 nits. That level already allows for a real HDR effect and in many films it does deliver a noticeably more appealing picture than in SDR. However, it’s not a level that dazzles by brightness alone. The A400 Pro is not one of those TVs that bombard the viewer with a powerful flash in every dramatic scene. The biggest limitation is visible with small bright elements on a dark background. Because of fairly aggressive zone control, the TV can significantly reduce their brightness, in extreme cases down to around 100 nits. That means small lights, sparks, stars or single highlights can be much less visible than they should be. It should be added, though, that this isn’t done without reason. The A400 Pro does this to keep black levels as deep as possible and to limit the halo effect around bright objects. It’s a deliberate compromise: the TV more often opts for deeper blacks rather than maximising point highlights. On the one hand this is understandable, especially given a limited number of dimming zones, but on the other you should be aware that the HDR effect won’t always be as strong as the peak brightness alone might suggest.

On the plus side, the colours are a strength. The PFS LED filter used here, marketed by the manufacturer as QLED, delivers suitably saturated colours. Our measurements showed about 94% coverage of the DCI-P3 gamut and around 74% of BT.2020, which is a solid result for this class.

We primarily tested the Sony Bravia 3 in movie mode, which immediately turned out to be the best choice among the factory settings. It's not a perfect picture, but compared to the eco mode that the TV suggests straight out of the box, the difference is evident and definitely better. In movie mode, there is a noticeable issue: the picture seems too warm, which is due to the lack of blue colour in the white balance. Nevertheless, in SDR content, the final effect can still be considered quite decent and satisfactory for everyday viewing. Much more serious errors arise in HDR materials. The Color Checker analysis showed significant deviations, and poor brightness management, combined with limited colour gamut coverage, further exposes the shortcomings of the picture in this mode. All of this makes HDR on the Bravia 3 look unconvincing and can ruin the impression left by the otherwise quite decent SDR content settings. Fortunately, it’s not a hopeless situation. Various errors can be somewhat mitigated, and some can even be completely corrected through professional calibration. That's why we decided to check how the TV would perform after such adjustments.

As usual, we carried out colour measurements in the best‑tuned picture mode, Filmmaker Mode, the one intended to be closest to the creators’ intentions. The A400 Pro, of course, also offers other picture modes, but in practice they show much larger colour errors and interfere more with the image character. So we won’t cover them in detail in this part of the review. How does the factory colour reproduction fare? In short: really very well. In fact, looking at our measurements, it’s excellent. Both the white balance and the luminance response were set surprisingly precisely. The errors were so small that during the measurements we genuinely rubbed our eyes in surprise. Such good factory settings don’t happen often, even in televisions running Filmmaker Mode. All the more reason to praise TCL, because the A400 Pro straight out of the box can produce an image very close to how the source material should look. The results were so good you could easily think someone had already given this unit extra attention and tried to calibrate it. Our one bit of nitpicking comes down to a single issue. In SDR material the image was slightly brighter than the reference for a dark room, because the factory gamma was set closer to 2.3 than 2.4. It’s not a large error and most viewers probably won’t even notice it. We should note, however, that we are talking about our specific test unit. There can always be some variation in factory colour between individual units, production batches or screen sizes. We do not assume every A400 Pro will look identical straight out of the box.

Calibration allowed us to extract significantly more from ChooseTV 3 than we could have expected at the beginning. First and foremost, it managed to address the deficiency of blue, which previously caused a noticeable warming of the image. After a slight adjustment in white balance, most errors in the Color Checker measurements for SDR content practically disappeared. The whites took on a natural tone, and brightness management in gamma stabilised to an almost ideal level, not exceeding the threshold of what the human eye can perceive. So it is safe to say that in SDR content, after a few adjustments in the settings, ChooseTV 3 performs really well. It fares much worse, although still definitely better than before calibration, when it comes to HDR content. The white balance has been brought in line, but the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which is immediately noticeable. Colour-wise, the effect has also improved, although it is far from perfect – many errors still exceed the threshold of four, and even five delta E units, remaining visible to the human eye. It was already clear earlier that ChooseTV 3 is not a television designed to impress with HDR quality. Nevertheless, it is pleasing that in SDR content, after calibration, the picture can look really great and in this category, the television pleasantly surprised us.

Despite the outstanding factory tuning, we couldn't resist checking how the TCL A400 Pro would respond to professional calibration. With such a strong starting point, we were especially curious whether we could squeeze even more from this TV. And here we have to boast: we managed to bring our sample to absurdly low colour errors. Results below 1 are something you don't see every day, even on very good TVs. Such outcomes are more often associated with professional reference monitors than with a lifestyle TV for the living room. In terms of white balance and colour reproduction, the A400 Pro after calibration simply excelled. The only thing we can pick on after closer analysis concerns the brightness response. The TV can vary the luminance level depending on the content being displayed, and quite often the picture is a little darker than it should be according to the reference. This most likely stems from the way the Mini-LED backlight and the local dimming algorithms work in this model. That said, it doesn't ruin the overall impression, because in terms of colour precision the A400 Pro after calibration reached a level that was genuinely hard to expect.

Bravia 3 brings something more to the Sony television family than just a shared name. It stands out primarily for its ability to enhance the quality of weaker materials thanks to the processor used. Of course, we won’t find the advanced XR chip known from more expensive models here, but nonetheless, it must be said that the image in lower resolution looked surprisingly good. The scaling worked effectively, and most areas of the screen were free from the typical excessive edge roughness found in budget constructions.

Also worthy of attention is the function that improves the smoothness of tonal transitions. In high setting, it works really well, effectively masking gradation imperfections without significant loss of detail. It does happen that the algorithm overzealously smooths elements that should remain sharp – for example, faces – however, in the overall assessment, the effect is beneficial. The best results were achieved precisely at the highest setting, and this is the option we could recommend to those watching lower-quality content.

Digital image processing is unfortunately one of the weaker points of the TCL A400 Pro. That does not mean the TV performs badly, but it’s hard to call it anything clearly above standard. The upscaling itself is acceptable: edges are fairly well smoothed, the picture does not look overly sharp or “pixelated”, and lower-quality material can be watched without major discomfort. At the same time the overall image has a slightly soft character and you don’t see the kind of precision that the best image processors in more expensive TVs can offer.

Handling of tonal transitions caused by heavy compression is much worse. TCL equipped the A400 Pro with a “Gradual Smoothing” feature that in theory should reduce visible colour banding and artefacts in lower-quality material. In practice, however, its effectiveness is very limited. It does not improve tonal transitions in any noticeable way, and at higher settings it can further smooth image detail, giving it an artificial, slightly blurred character. For that reason we think it’s best to leave this feature off. The A400 Pro copes decently with basic image scaling, but if you often watch heavily compressed material with visible posterisation, this model will not be one of the best choices.

Motion smoothness has never been a strong point of televisions equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has included something that may appeal to those more sensitive to the way images are displayed. I'm talking about the proprietary motion smoother, Motion Flow, which gives the user plenty of adjustment options. With it, one can make the image smoother, almost theatrical, or stick to a more cinematic style with characteristic judder that many people simply associate with a filmic atmosphere. These functions work with content at lower frame rates, such as films and series recorded at 24 or 30 frames per second, which is the material we deal with on a daily basis. This is precisely where the motion smoother proves to be one of the most important features in everyday TV usage, and here, the Bravia 3 performs really decently.

The TCL A400 Pro is equipped with a 144 Hz panel, but in practice we're most interested in how it performs at 120 Hz. That's the refresh rate most consoles, as well as many sports broadcasts and high-motion sources, are limited to today. In that range the TV performs quite well. Motion clarity is really good, especially after properly configuring the motion smoothing. The 'Motion Clarity' function improves smoothness. Its settings include two sliders that let you tailor the motion smoothing to your preferences, separately for low-frame-rate and high-frame-rate content. This allows you to achieve either a more cinematic look or a noticeably smoother image. If you don't want to fiddle with manual configuration, you can use built-in presets such as Low, Medium, High, Cinema or Nature.

Bravia 3 is not gear for e-sports enthusiasts or fans of late-night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports shuts down the conversation before it even gets started. This is a TV for casual gamers who, after work, will fire up FIFA or racing games, not for someone who measures every frame in a spreadsheet. Nonetheless, Sony has thrown in a few nice additions so it’s not completely sparse. ALLM works as it should, automatically switching the TV to game mode (low latency). We even find a simple Game Bar here, which is clear and intuitive. However, the biggest curiosity here is the PlayStation Portal app. Thanks to this, you can launch PS5 games wirelessly and see them right on the TV screen. It sounds great, but it only takes a few minutes to feel significant lag. In our opinion, it's more of a showcase of capabilities than something that can be used day-to-day. If someone really wants to game, it's better to plug the console in with an HDMI cable and forget about wireless issues.

In terms of gaming features the TCL A400 Pro performs brilliantly. The TV has practically everything you’d expect from a gaming TV today: support for 4K at high refresh rates, VRR, ALLM, correct implementation of HDR formats in games, including Dolby Vision, and HGiG. That means it works well with both next‑gen consoles and PCs. Another plus is the inclusion of a Game Bar, a dedicated panel with the most important settings for gamers. From it you can quickly check basic information about the signal, refresh rate or active features, and customise the appearance and behaviour of some settings to your preferences. It’s a solution that may not change picture quality by itself, but it greatly improves the convenience of using the TV while gaming. The only thing to criticise is the number of full HDMI 2.1 ports. The A400 Pro has only two such ports out of four, and one of them also serves as eARC. In practice this means that if you want to connect two next‑gen consoles and a soundbar you may run into some limitations. In that scenario you’ll need to either swap devices or use extra equipment, such as an AV receiver or a soundbar with HDMI inputs. Even so, it’s hard not to rate the A400 Pro very highly as a gaming TV. The gaming feature set here is genuinely powerful.
